Abstract

Advances in processing capability have far outpaced advances in I/O throughput and latency. Distributed file system based storage systems help to address this performance discrepancy in high performance computing (HPC) environments; however, they can be difficult to deploy and challenging to maintain. This thesis explores the design considerations as well as the pitfalls faced when deploying high performance storage systems. It includes best practices in identifying system requirements, techniques for generating I/O profiles of applications, and recommendations for disk subsystem configuration and maintenance based upon a number of recent papers addressing latent sector and unrecoverable read errors.
